What is a passive home?
The term “passivhaus” comes from Germany where these originated from back in the 90s. This method of building takes advantage of designs that draw on sunshine, shade and ventilation and they uphold a comfortable temperature without having to use as much energy as a traditional home. This stands for both cold and warm temperatures.
How does a passive home work?
- High quality insulation
- Superior Windows
- No thermal Bridging
- Airtight construction
- Mechanical ventilation
Passive homes and its benefits for a more sustainable and comfortable future
- Lower carbon emissions
- Warm, snug rooms without any draughts or cold spots in winter, and cooler rooms in summer
- Cleaner air quality inside
- Low maintenance costs
- Peace and quiet when the windows are shut
- More wall space, as you don’t need any radiators
What are the requirements for a Passive Home?
- Space heating demand
- Primary energy demand
- Airtightness
- Thermal comfort
How much heating does a passive home need?
Due to the high level of energy efficiency, the heating demand in Passive Houses (typically no higher than 15 kWh/(m²a)) is only about 10% of the energy used in conventional buildings.
